| Shortcomings of the traditional education mode communication is mainly embodied in the education information island and resource sharing not timely, statistics report of inconvenience, and many other aspects. In order to overcome these deficiencies in traditional education information communication mode, based on the Internet platform, all countries in the world in continuously boost the informatization of education industry. Now, the degree of education informatization has become a important measure of the development level of national education. Therefore, in order to achieve the strategic goal of developing the country by relying on science and education, realize the modernization of education, high-efficiency, rationalization, further improve the quality of education, the need to vigorously promote the education informatization construction. Though education informatization of our country starts relatively late, but after more than ten years of development, has had great progress.According to certain place, the existing education public service platform, to the education of public service existing business and information needs analysis, give full consideration to the actual needs of the different participants in the education industry, the education information release, daily administrative management and education quality evaluation and remote teaching requirements for analysis. In the traditional Chinese education teaching practice, the concept already thorough popular feeling. Therefore, in this paper, in the process of demand analysis, despite previous exam-oriented education’s emphasis on "teaching", but more focus on the fundamental need of "learning". Through field visits and sampling survey of students, system analysis of the needs of students, and hope that the designed system can maximum limit arouse the enthusiasm of students learning, by passive learning into active learning. In under the guidance of the idea, this article discusses the "education cloud network" public service platform project background and need to solve the problem, through the functional requirements and non-functional requirements two aspects to analyze system requirements, and in the form of a use case diagram to elaborate.Combined with the requirements analysis phase is summarized the actual business needs, we are "education cloud network" public service platform of the underlying technical architecture design and demonstration. We according to the system requirements, and the application of foreseeable service scale, developed a platform construction should follow the principle of and the final goal. Then respectively on the system of the technical architecture and application architecture design. The service object of the system is facing numerous and diverse business, the technologies used in choosing the technical architecture, we mainly consider the concurrency requirements of the system, as well as the robustness, extensibility, maintainability and performance issues. In the end we chose based on the MVC model, conform to the requirements of the enterprise applications, conforms to the J2EE specification RFRAME platform. In the technical architecture discourse to RFRAME platform function of each layer are introduced. In application architecture design, first discusses the overall system model structure, the whole model structure is analyzed based on the system of "education" cloud network application framework design demand of public service platform, combining with RFRAME platform advantages designed "education cloud network" public service platform.And then step is "education cloud network" the detailed design of public service platform. This part firstly design the overall system structure, system function menu. And then analyzes the portal website backstage management the key module. In system design in detail, in order to more clear explanation "education cloud network" the overall functional design of public service platform, our system can be divided into three directories, presents a directory of the module function at different levels. After understanding the function of the overall structure, expounds the portal website background management subsystem detailed design.Next, we rely on before the detailed design, has carried on the simple to the concrete realization of each main module, and shows the final overall construction results. And then focus on the RFRAME platform realization of data paging query component are expounded.In the following chapters, is described in detail in "education cloud network" public service platform project test link in the related concepts and methods.Finally, this article on "education cloud network", the application of the public service platform introduced some, and in view of the problems found in practical application, puts forward some improvement opinions, aims to promote further perfecting of the system.From what has been discussed above, we on the basis of demand analysis, designed and implemented a comprehensive information platform is suitable for the education of the public services, to promote the education informatization construction has made the beneficial attempt. |
